E63 / E64 6 Series (2004 - 2010) The E63/E64 BMW 6 Series builds on BMW's sporty heritage with aggressive lines and an incredible motor to back the design up. Available in coupe and convertible trims with a standard 4.8 liter engine producing 360 horsepower and 360 lb-ft of torque, the 6-series is a popular choice that exceeds expectations.

My fluid was pretty dark before I changed it. I thought the color was light green but as long as it's not dark you are OK. That system does more than just power steering and it does take a fair amount of fluid to fill it and uses some occasionally. Not sure why though.

When I checked it and it was dry, my car had been sitting for a few hours. I drove to get the fluid, and when I went to top it off the reservoir was almost full to the max line on the dip stick...Are you supposed to start the car before checking it or something? I only had to add just a tiny bit...

Check your owners manual for the procedure. It seems to differ from car to car.

My fluid is a brownish color. It sounds like different manufactures use different color dyes. As long as you have the CHF-11s fluid, you should be ok. If you keep losing fluid, I would try & find the leak fast. Repair cost could be astronomical!
